It was loudly soiled work clothes After washing with leave put on work clothes of the pocket. It might be recommended for those who write the fine character. I purchased the wrong without knowing the ultra-fine.

I, because the fast writing, is not good and not a Mitsubishi Uni-Uni-ball. Also used jet stream, but it is recently often use the Uni-ball. To ink reservoir there is no such as a ballpoint pen, it is easy to write fluently. Famous pen with a third-party popularity also tried but is not this about my speed. On the other hand, this Uni-ball is, comes with no be blurred even in ultra-fine type. It is recommended by all means you are in the fast people.

Schedule and write, I use on the job. Until it encounters in this pen, I did not have it was only with those of 0.5mm. Not too thick not too thin, writing feeling the best. Writing of the notebook to such also, character is not collapse, I like. Until the pen that was used, I have often feel light stress at or longer written to remain ink This is off to use up to the last, is pleasant.

I am using it for a long time. I can write it as a slasher with a light writing pressure, and I like the copy form of the invoice such as the delivery note so I can clearly fill in it very much. Since I started using this product I have not used any conventional ballpoint pen.

It's easy to write and looks beautiful. I feel that ink reduction is fast. When filling in duplicate paper or thin paper I feel that the paper is easy to cut and ink is not good. You can use it without problem as a paper quality like ordinary copy paper.
